Detailed inventory data (n = 3,930; approximately one representative sampling point per 650 ha) on soil organic carbon (SOC) to a depth of 30 cm has been used to characterize carbon content in forest soils in the Czech Republic across all altitudinal vegetation zones and forest ecological series. This data set was used to predict the most probable changes in soil carbon content in the altitudinal vegetation zones due to global warming. The mean value of the SOC content in forest soils of the Czech Republic was determined to be 62.6 ± 17.2 t.ha-1. Under different warming scenarios the major SOC loss was observed at an altitude...

There is little knowledge available regarding Australian forestry work safety and accident rates. Machine operators and forestry workers are vital parts of the forestry sector and their health and well-being can greatly impact on their work quality and efficiency. To increase our knowledge of forest workers' safety this project aimed to analyse the frequency, type and root causes of work accidents which occurred within different forestry activities of five industry partners of Australian Forest Operations Research Alliance over the period from 2004 to 2014. A questionnaire was designed and distributed to the partners to collect the safety incident...

Decline of the Zagros forests of western Iran dominated by oak trees is assumed to be highly connected with changes in meteorological parameters. To examine this hypothesis, we aimed at observing the long-term trends of meteorological parameters and reference evapotranspiration (ET0) in the Zagros region. Long-term (1961-2010) data of air temperature (Ta), relative humidity (RH), precipitation (P), and wind speed (WS) were obtained from meteorological stations located in the Zagros region. The Penman-Monteith equation was applied to calculate ET0. The results indicated that...

Biological diversity is the basis for a wide array of goods and services provided by forests. The variety of forest trees and shrubs plays a vital role in the daily life of forest communities. The purpose of this study is to investigate the possibility of modelling the diversity of tree species by characteristics of topography, soil and climate, using data mining algorithms k-NN, RF and SVM in Dr. Bahramnia forestry plan in the north of Iran. Based on the basal area factor for each species in a total of 518 sample plots, diversity indices such as species richness, evenness and heterogeneity were calculated for each plot. Topographic maps of...

The purpose of this paper is to develop a method of constructing density distribution charts in roundwood log based on the density values obtained with a resistograph. The problem of improving the performance properties of structures made of wood and wood-based composite materials and laminated products is particularly relevant for construction in the northern regions. The experience of building in Yakutia shows sufficient reliability and durability of structures made of larch wood, despite the fact that their use is associated with technological challenges: larch planks warp and crack during the drying process; rigidity of wood increases. These disadvantages...
